To all whom t may concern:

Be it known that I, LA VERNE NoYEs, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinoisyhave invented a certain new and useful Improvement in Windmills, of

'which the following is a full, clear, concise,

and exact description, referencel being had to the accompanying drawings, forming a part of this specification.

My invention relates to wind mills and has a number yof objects and advantages in view.

By means of my invention I am enabled to reducefriction between some of the engaging relatively movable parts. To this end the force which is employed to furl the mill and actuate the brake is applied in an upward direction longitudinally of the tower, such force tending to lift the mill head from rather than press it toward its step bearing, though the invention is not to be limited to this method of adjustment. In carrying out the invention, the furling mechanism desirably applies the brake during the final part of the vane folding movement.

I will explain my invention fully by reference to the accompanying drawings showing the preferred embodiment thereof and in Which- Figure l is a view in elevation, partially in section, of a wind mill embodying the invention; Fig. 2 is a somewhat diagrammatic view showing my lever arrangement; Fig. 3 is a view on line 3 3 of Fig. 1; Fig. 4 is a view in elevation of the upper part of a mill; Fig. 5 is a view on line 5 5 of Fig. 3; Fig. 6 is a detail; and Fig. 7 is a detail.

Like parts are indicated by similar characters of reference throughout the different figures.

rIhe wind wheel 1, having a horizontal axis, is mounted upon a shaft which carries spur pinions 2 in mesh with spur gears 3 that operate pitmen 4: having connection at their upper ends with the load rod 5. The wind wheel is mounted upon a mill head 6 which is afforded an upright axis of rotation by being mounted upon the shouldered,

end of a stationary vertical pipe 7 at` the upper end of the mill tower and through which pipe the load rod passes.

The mill yvane 8 is journaled at 9 upon the mill head to'swing about an upright axis, the

vane being moved toward and from the wind wheel when the latter is res ectively to be placed out of and inthe wind), sprinfr buffers 10 cushioning the vane in the'ina portionsl of its swinging movements.

1 1 swinging arm 11 is afforded an upright axisof movement by being mounted upon a vertical bearing shaft 12 fixed upon ,the mill head with the load rod between and preferably substantially equidistant from the mounting shafts 9 and 12. The long branch of arm 11 is flexibly connected with one end of link 13 whose other end moves a finger 131, operatively forming a part of the link, which operates to engage and move the vane toward the wheel in the furling operation, but from which linger the vane may move toward the wheel in governing. A lever rod 14 connects a vertically movable furling collar 15 with the arm 11 near the connecalso preferably a rod.A The vane shaft 9 is located between the vane ends of rods 13 and 16 that afford flexible connection between the furling collar 15 and the outer ends of an arm 81 pivoted between its ends upon upright shaft 9. In the furling operation, link 13 pulls upon one end of arm 81 and rod 16 pushes upon the other end of this arm to cause linger 131 to push the vane 8 to a closed position. The form of flexible connection between the rod 14 and arm 11 and of lever rod 16 with the arm 81 may be generally of the nature illustrated in Fig. 6. The lower ends of lever rods 1 4 and 16 are bent to extend horizontally there to be journaled in horizontal bearings 17 formed on top of the furling collar 15 and on opposite sides of its axis and equidistantly from its center. The collar 15 is in assembly with a lianged sleeve 18 (loosely suriouiiding pipe 7), the ange of the sleeve 18 having connection with the upper ends of push rods 19 whose lower ends are connected with one end of a lever 2O whose other end carries a pull wire 21 accessible from the ground. The collar 15 and the rods 14 and 16 will turn with the head and with reference to sleeve 18 which is only vertically movable. IVhen vthe wire 21 is pulled downwardly (after which action it is hooked at its lower or ground end), the rods 19 are consequently pushed upwardly to cause the iange of sleeve 18 to push the furling collar up, to

swing the mill vane from its position when the' wheel is in the wind to a position in which the wheel is out'of the wind, thislatf ter position being indicated by dotted lines in` Fig. 2. Because of the illustrated location of the shaft 9 between the adjacent ends of lever rods -14 and 16' and the manner in ment with the sleeve 18 and the sleeve will not have binding engagement with the pipe. The arm 11 of the furling mechanism is also instrumental in applying braking pressure to the .wind wheel when the vane is nearly completely folded Atoward the wheel. For this purpose the arm 11 hasa short branch 22 adapted to ride upon the free end of a spring brake band 23 which passes about the brake drum hub portion 24 of the wind wheel and has its anchored end secured to the mill head.

In order that the wind mill may be properly sensitive to changes in direction of the wind it is essential for the mill head to turn upon its vertical axis with the utmost freedom. By making use of an upward force transmitted through the push rods 19, furl- -Aing of the mill is accomplished without increasing the frictional resistance with the vturning of the mill head upon its bearing.

rllhe pressure applied to the furling collar 15 is removed from rather than exerted upon the step bearing. Similarly the braking force, upwardly applied, is not exerted upon but is removed from the step bearing. When the wheel is in the wind the push rods 19 will drop suliiciently to space the flanged sleeve 18 vertically apart from the furling collar 15 to an extent that will eliminate material frictional contact between this sleeve and collar while the mill head is turning. When the mill has been furled by the upward movement of the furling collar the lever rods 14 and 16 have been brought almost to the horizontal so that the downward pres'- sure exerted by them is very slight and consequently the pressure tending to produce friction between the furling collar, when ro' tating, and flanged sleeve is correspondingly small. In one broad aspect of the invention, therefore, the flanged sleeve and the pushing rods 19 constitute a pushin element, which when pushed upwardly, w1ll furl the mill and apply the brake,though the invention is not to be limited toa construction in which the rods 19 are pushed.

WhileI have herein shown and particularly described the preferred embodiment of my invention .I do not wish to be limited to the precise details of construction shown as changes may readily be made without de-l parting from the spirit of my inventiombut Having thus described my invention I claim as new and desire to secure by Letters Patent the following I 1.
